ABSTRACT

A floating beverage container that remains substantially upright when placed in liquid, and continues to function well when placed in a cup holder or other substantially flat surface, including a floatation compartment releasably attached to a ballast chamber. The floatation compartment includes an interior surface including multiple inner diameters and a tapered upper section to accommodate many types of beverage containers. The ballast compartment has a substantially flat bottom surface.

BACKGROUND

1. Field of the Invention

The present invention relates generally to a universal floating beverage holder, and more particularly to a floating beverage holder that remains substantially upright when placed in liquid, and continues to remain upright when placed on a flat surface.

2. Description of the Related Art

There is a compelling need for an improved floating beverage holder. Previous beverage holders efficiently accommodate only one particular dimension of beverage and are designed to function solely in the water, while not being able to remain upright when placed on a substantially flat surface, such as a cup holder, a side of a pool, or the surface of a boat.

People who engage in recreational water activities such as swimming, floating, fishing, boating, or other activities on or near the water frequently desire a holder for their beverage. Previous beverage holders, such as those described in U.S. Pat. No. 8,025,146 would not remain upright when placed on a flat surface.

Other floating beverage holders accommodate only a single size of beverage containers. Beverage containers frequently come in varying sizes such as aluminum cans, glass bottles, plastic bottles, and plastic cups. Beverage containers also come in various shapes and sizes including twelve ounce, sixteen ounce, eighteen ounce, twenty ounce, and twenty two ounce containers, among others. Previous attempts to improve beverage holders, such as those described in U.S. Pat. Nos. 7,972,063 and 6,991,505 have resulted in only marginal improvements.

Therefore, it is desired to provide a universal floating beverage holder that remains substantially upright both when floating in liquid, and when placed on a flat surface such as a cup holder or other substantially flat surface.

SUMMARY OF THE INVENTION

To achieve the foregoing, and in accordance with the purposes of the present invention as embodied and broadly described herein, it is an object of this invention to provide an improved floating beverage holder.

Another object of the invention is to provide a beverage holder that has an interior surface having multiple inner diameters, including a tapered interior surface. This enables the beverage holder to encapsulate varying sizes and shapes of beverages while remaining upright while floating in liquid and ensuring the contents of the beverage will not be spilled or contaminated by the liquid.

The universal floating beverage holder features a design and construction that makes it simple and inexpensive to manufacture.

Therefore, the present invention provides a sufficient orientation, density, and distribution of both flotation material and weight such that that various sizes and weights of beverages are held upright while in liquid or on a flat surface.
